Indications for concrete paver installation, complying with the standards

●
It is assumed that the concrete paving stone installation units (layers of pavers), which are to be laid, comply
with the requirements allowing a uniform laying pattern, complying with the standards.
●
It is assumed that the concrete paving stones, which are to be installed, will be furnished with the so-called
spacer bars having a thickness of at last 2,5 mm.
●
Optimum condition can be taken for granted due to the use of pushing-off device ADV. Individual pavers
cannot cock during the installation process, they are laid exactly. When pushing-off layer after layer into the
bedding sand an additional but slight joint space results between the individual pavers in gripping direction
from propping at the upper edge of the pavers.
After the installation process these additional but slight joint space mustn't be hammered together with a
rubber hammer in bedding sand direction not at all. After the installation process the individual pavers of the
freshly laid paver layer unit have to be slightly dispersed, most suitable to be done with the shoes from the
person who is doing the alignment.
Only that way a joint complying to the standards with a size of 3 - 5 mm can be achieved.
In case of some initial manual paver laying work might be necessary before actually starting with the
mechanical laying area, the correct spacing of the paving stone installation unit has to be sticked to during
manual laying process.

●
Correct gripping range adjustment of the side gripping (adjustment P) guarantees that the individual pavers in
gripping direction will not be firmly pressed together, but rather have a slight additional joint space in side
gripping direction.
When the laying action has finished, in no case knock together (from the facing bedding sand ) these slight
additional joint space with a rubber hammer. These slight additional joint space is necessary to get a normal
joint between 3 to 5 mm.
When before beginning with a machined laying, a laying by hand is necessary, the structural modules of the
laying unit must be observed.
